Great value but still a very good amp as well

I wanted to wait till I had it installed for a couple weeks to do a review and now that the time has passed I can say that i am supremely satisfied with my choice.

I bought this one to replace the 5-channel PPI-Phantom amp that is now going in my wifes Mustang.

I have never owned a true top of the line amp, or even one of the top brands that are 'expensive' compared to this amp and the PPI.

There is no doubt that it does the rated power as it blows the PPI out of the water and the set-up was rather simple as well, does not seem to be many bells and whistles but I am very happy.

And it has a 2 year warranty which I extended for a year through the manufacturer for nominal fee.
